vfor spreading sand o1i-rcads.

'l`hc object of the invention is to provide an apparatus for spreading .sand evenly over a large area.

'l`he device is primarily intended for use ,in spreading sand over the :airfares of roadways which have been previously coated with oil. tar` or similar substances in an adhesive or sticky conditicn.

`With the above object in'view. the apparatus comprises a vehicle which is adapted to follow the wagon which applies the liquid to the roadway, and is provided with means for discharg'inzgr the sand in a broad stream or sheet evenlyy over the' coated surface of the roadway. This sanding ve'hicle body l is supported on the rear axle C upon Iordinanv wagons or'nioto'r vehicles.

which the rear wheels t3 are These wheels are provided with wide tiresand their gage is substantially that of 'llicl'rcnt wheels l may be Araged .so that the outer edges or their tires are substantially -in liuc with the inner edges of the tiles on This invention relatesto an apparatus` the rear wheels. Thus as the vehicleuunes` over the road it rolls a comparatively wide track in the sand which has been spread, n and thusl aids in torming a smooth, finished surface.

The vehicle may be propelled by any suit-- ible motor il) connected by sprocket chains il to sprocket. wheels 12 on the rear wheels t3. The front wheels t are steered by the hand wheel il in front lof the seat 15. This hand wheel 'is mounted on a `shaft lt which carries an arm 1T pivotally connected bya i crankarm 1S to a rod 19. which in turn is pivotally connected to a crank arm :'20 on may be attached to the rear `of the liquidcarrying vehicle, or it ma)7 be 'self-propelled. Itis impossible to draw the` sandiulcr appliance byv horses attached directly thereto. for the reason that their feet would become greatly fouled by the liquid on the road; so Athat the preferred embodiment ot' the invention comprises a self-'propelled vehicle. althouglrit is not limited thereto.

The invention consists in the sanding apparatushereinafter described and claimed. the advantages of which will be obvious to those skilled in the art from the following description. In the-accompanyingr drawings Figure l is a side-ele 'ation of the apparatus, Fig. 2 is a front elevation of the same. partly in section, Fig. 3 is a sectional elevation taken on the line 3 3 in Fig. fl, and F l is a plan view of the apparatus. p

)is illustrated in the drawingsV the apparatus comprises a wagon body l pivotally' supported at?! upon the front frame 3, to lwhich the. steering axles are connected -npon which the front wheels l are mounted. The purpose of thuspi'fotally li'uounting the body l is to enable it to be tilted as shown bythe dotted lines in Fig. 3, to facilitate thelforward feeding of the sand, as will be hereinafter ex'plained. The rearv end of the the upper end of a shaft- 2l joui-tailed in a bracket 22 secured to the wagon body. .i crankarni is se fared to the lower end of .the shaft 21 and is pivotally. connected to mount-cd.

one end of a rod 2l, which in turn is pivotally connected to the stceriner knuckle 25 of the front axle.

The sides of the body are tlared at il() and 31 to increase the width of the body at the front end.. Said body is divided by a transverse partition :'32 into a sand co1upart-nient 33 and a brush compartment 2li. An opening extends through the lower edge of the partition 232 to enable the Saml to pass from the. sand compartmentto the .brush compartment.- The amount of sane fed through this opening may be regulated by a slide Sti mounted upon the fronteidt of the partition 32. Thisslide i? Controlled by a handle 2li' secured to a sha't't-38`-and havirna .sliding rod 39 adapted totengage a toothed sector t0 to hold the handle 3T in A. crank arn'i. I is Sez fired to the other end of the sliaftlS and is connected b v a link t2 to a., crank t3 on ii 4shaft. Jet extending' the length of the brush compartment.h i

linksffl to .brackets -tT ou'theslide Bti'. -l nurvrng' the handle 3T forward or back the slide Clo maybe lowered er raised as der sired. and then held in-`adiusted position by'the-engagement of the rod 39 with the rack 40.

."t pair ot crank arms t5 aresecured 'to 'this shait and conne fled by lon tot

455 which carnes a bevel gear 56. The bevel gear 56 meshes with a bevelvgear 57 on one end of a shaft 58, having a bevel gear 59 at its other end. The bevelgear 59 meshes with a bevel ear 60 on a shaft 61 which is provided wit 4a bevel gear 62 slidably mounted thereon and meshing with Aa bevel gear 63 on the brush shaftG/l. The brush may be thrown into or out of action by a handle 66 connected to a shaft v67- which is provided with a crank varm 67 connected by a link 68 to one end of a lever 69, the

other end of which is connectedto a groovedn vboss on the gear 62. A rod 70 on the handle 66 engages arack 71 to hold the handle in adjusted position.

The rear end of the body 1 is raised and lowered by the following mechanism A screw 80 is pivotally supported upon rear axle 5 and projects through the bottom of the body about 'midway thereof. A casing 81 covers the screw to prevent the sand from gaining access thereto. A 'nut82 is threaded on the screw and formed with a worm wheel 83 which meshes with a worm 8A on a rod 85 mounted' in bearings in the bottom of the body. The nut 82 bears against a plate 86 on the bottom of the body, and as. the nut rotates the body is raised or lowered. The

vrod 85 is provided with a bevel gear 87 which meshes with a bevel gear 88on one end of a shaft 89, the other-end of which is provided with va sprocket wheel engagingv a chain 90 coperating with avsprocket wheel v9,1 on one end of a shaft 92, the other `end of which is rovided with a crank handle 93. By turning the handle 93 the nut 82 is rotated by means of the mechanism just recited'. y

From the description above set forth it will be seen that the wagon lbody may be inclined as desired to feed thesand toward the brush, and the amount of sand fed into the brush compartment can/ be regulated, 'thus regulating the dischar e through the opening in the front of the machine, and

all of the mechanism can be operated from the seat.

While I have illustrated and described a preferred embodiment of the invention, I`

am aware that many modifications can be made therein by any person skilled lin the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction shown and described,

but

What I claim is 1. In an apparatus for sanding roads, the

combination of a wagon body having a sand compartment and a brush compartment, a

brush mounted 4to rotate in the brush com-y partment, a seat at the frontof the body, means operable from the seat for raising the rear lend of the body,'and means throu h.

the rear portionof the wagon body, a seatl on the wagon body, means operable from Vthe seat for raising the rear end of t-he body to facilitate the feeding of the sand from the sand compartment, and means controlled from the seat for regulating the amount of sand delivered from the sand compartment. 3. In a device ofthe character described, the combination of a running gear, a ver hi'cle body mounted upon the running gear and having one end thereof flared laterally so as to project beyond the running gear, a brush compartment being formed in t e flared end of the vehicle body and the said brush compartment communicating with the vehicle body and being provided with a discharge slit, a brush mountedI within the brush compartment for forcing material through the discharge slit, gearing between the running gearand the brush, a seat upon the vehicle body, means operable from the seat for throwing the said gearing into and lout of action, and means also operable from the seat for tilting the vehiclebody to cause material in 'the same to flow into the brush compartment. In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
